Actually, I used a grey balance reflector (similar to a grey card) so the original had more realistic skin tones but I tweaked the piss out of it in photoshop.

I guess one of the main things people in here are commenting about is my liberal changing of the color values - particularly on the skin. Since it is not apparent I did this on purpose I failed to do it correctly. Also, It is clear that i need to practice getting more appealing poses out of my models.

Thanks for the comments guys, you have all given me a lot to consider for future shoots =)
